QA/G-5 provides guidance on developing Quality Assurance Project Plans (QAPPs) that will meet EPA expectations and requirements. This document provides a linkage between the DQO process and the QAPP. It contains tips, advice, and case studies to help users develop improved QAPPs.

This checklist is designed to be used when reviewing Quality Management Plans prepared according to EPA QA/R-2 EPA Requirements for Quality Management Plans. While the primary purpose of this checklist is for internal agency review and approval of Quality Management Plans, outside parties that need to prepare Quality Management Plans may find this checklist useful. Some of the checklist items may need to be adapted, when reviewing Quality Management Plans prepared by outside parties.

QA/G-4 provides non-mandatory guidance on developing Data Quality Objectives (DQOs) using a systematic planning process based on the graded approach. The guidance presents a step-by-step description of the DQO process. The Aug 2000 version supercedes the Sept 1994 version.
